S3 Weird Screen Lines - Unusable
A friend just brought me a Galaxy S3 to troubleshoot. It was in perfect shape, they took it to a phone booth to get it "unlocked" (the bands), it booted fine once and the second time the screen shows weird lines, it doesn't do anything else. Recovery mode doesn't respond.
KIES detects it but cannot connect to it, ODIN does not see it. Drivers are correct and another S3 has no problem with same PC and Cable. It shows up in computers device manager as "Samsung Mobile Device Modem". It does not appear with errors.
I am curious if anybody can help me determine the issue or the potential problem and if any solution is possible. I am unable to post an external link but the screen has strange lines with green, black, white background and red dots. It is not like a broken LCD where it's random, it's a controlled pattern
